The plant in pics 3 and 4 (I’m guessing the bigger one) has bracts/calyxes that haven't yet swelled up. It looks like it’s been hungry during flower, like it needed more K. Leaf edges are pale, leaves are pale overall, and the buds do have some size to them but don’t have a lot of density or swelling for this stage. The second plant looks a lot more finished and ready to go.
